It is a pretty sure bet that the Appalachian mountains pose no volcano threat. You see the chain was formed by the collisios of two plates of equal
density, leading to massive uplift a la the Himalayas. Now this really doesn' lead to much in the way of volcanism. For volcanoes you need either
subduction, like in the Ring of Fire, or a Hot Spot, like Hawaii. Now add to this the fact that the collision which created the Smoky Mountains and
the Appalachians is over and done with, and the chain is slowly being eroded to nothing, and your threat drops virtually to zero.
